This is exactly what I have and rate it well. 80mm thick or so when rolled out. I have the King Single. My wife has not been for years but if we planned a touring trip I would grab a second one and lay them together. The beauty of two of these v 1 double is the Doubles are Huge and full width when rolled and basically need to go on the roof. 2 king singles still fit in the car no worries.
Great value and ai also got it on special for around $70. At the time I couldn't find anything under $200 with this thickness and was Stoked when I stumbled on these. Would not hesitate.
